JOSEPH DANISCHEVSKI, OF ST. PETERSBURG, RUSSIA.

DEVICE FOR AUTOMATIC KINDLING OF INCANDESCENT LAMPS.

Application filed September 14, 1906.

To all whom it may concern:

Be it known that I, JOSEPH DANiscHnvsKr, a subject of the Emperor of Russia, and a resident ci' St. Petersburg, Russia, 141 Gagarinskaia street, have invented certain new and useful Improvements in Devices tor Automatic Kindling of Incandescent Lamps, of which the following is a specification.

The construction of the proposed device for the automatic kindlin of incandescent lamps (which may be ca led hydrostatic), is based on the fact that a certain time is required to ill a chamber with liquid, which ows through a thin tube or opening, which time may be determined exactly if the capacity of the chamber, the size of opening and the pressure with which the liquid flows are known. l/Vhen, after the elapse of a cer tain length of time, the chamber becomes filled and the liquid will iiow through a tube open at the upper end of the chamber, to the place where it is to be used.

Making use of such a method for feeding incandescent lamps with liquid combustible, the flow of the latterto the vaporizing tube may be regulated in such a way, that when kindling the lamp, the liquid should commence to enter the vaporiZer only after the latter has become sui'liciently heated by the flame of the alcohol contained in the cup under the vaporizer.

In the accompanying drawing, Figure 1 represents a vertical section of the device showing communication established between burner supply conduit and the reservoir. Fig. 2 is a similar section showing such communication cut off.

The liquid combustible flows from reservoir 1, into a conduit 2, which contains a suitable filter 3, for detaining foreign bodies and admixtures, contained in the liquid combustible. A conduit 5, communicates with the conduit 2 through a coupling 41 and leads to a casing containing a cock 7. When the cock is in the position shown in Fig. 1, the conduit 5 communicates with a lling tube 9, through a curvilinear slot 12 in the cock. This tube 9 enters a closed tank 6 through its bottom and terminates with a narrow opening near the top of the tank. A discharge tube 8 mounted in the tank 6 has its upper or receiving end opening above the Specification of Letters Patent.

discharge end of the tube 9. The lower or discharge end of tube 8 is in constant communication with a conduit 15, which supplies the vaporizer (not shown) by means of segmental passage 11, and passage 14 in the plug 7.

When the cock is in the position shown in Fig. 2, communication between the reservoir and the burner-supply conduit 15, is cut oiil and the liquid combustible in tank 6 will iiow therefrom into a catch tank 18 which communicates with the tank 6 through pipe 10, and passages 13 and 14 and 17 in the cock and communication between this catolitank and the burner-supply conduit 15 is established through passage 16 which now communicates with passage 14 of the cock.

The operation of the device for the automatic kindling of incandescent lam 9s is as follows: As is well known alcohol is placed in a cup under the vaporizing tube and ignited for the purpose of heating the tube. The cock 7 is at once opened, as shown in Fig. 1, when the liquid combustible will flow from the reservoir through conduit 5 into tube 9 and raising in the latter flows through the upper narrow opening into tank 6 and owing to the pressure from the reservoir the tank will become filled. By this time the burner will be sufficiently heated to vaporize the liquid combustible which will now flow into the pipe 8 and through the conduit 15 to the vaporizing tube and. the incandescent mantle will be ignited by the remaining flame in the cup. Upon turning the cock into the position shown in Fig. 2, the lamp is immediately extinguished by the `How of liquid from the tank 6 as previously described, which causes a suction at the inlet end of tube 8 which withdraws the liquid combustible out of the tube. This suction is aided by a dome 19 placed in the top of the tank directly above the tube.

I claim:

ln a device for the automatic kindling of incandescent lam s, the combination with a reservoir for a. iquid combustible and a burner conduit, of a closed tank, a-supply conduit communicating with the reservoir, a supply tube leading into the tank, a casing connected to the supply conduit and tube, a discharge tube communicating with the burner Conduit and tank, a dran in the name to this specification in the presence of latter, a cook in the casing to simultaneously two subscribing Witnesses.

connect the sup 1y tube and supply conduit and close the rain and to simultaneously JOSEPH DANISCHEVSKI' 5 disconnect said tube and conduit and open Witnesses:

the drain. H. A. LOVIAGUINE,

In testimony whereof, I have signed my EDWARD WANSCHEIDT.
